No, and you should have your meter zeroed on the left. The only step you zero in the center is nulling the discriminator.
Just flip to + or - DC volts to get it to deflect to the right.

OK I did that. Sweet spot looks like a 21.25mc input at 68mV and peaked on the 5V VTVM scale at this point. Any movement of the primary adjustment either way results in a lower reading.



Does this sound and look about right?
